User Notes:
—————————————-

– ### AMI: Add parking position parameter to Park action
New ParkingSpace parameter has been added to AMI action Park.

– ### res_musiconhold: Add option to loop last file.
The loop_last option in musiconhold.conf now
allows the last file in the directory to be looped once reached.

– ### AMI: Add CoreShowChannelMap action.
New AMI action CoreShowChannelMap has been added.

– ### sig_analog: Add fuller Caller ID support.
Additional Caller ID properties are now supported on
incoming calls to FXS stations, namely the
redirecting reason and call qualifier.

– ### res_stasis.c: Add new type ‘sdp_label’ for bridge creation.
When creating a bridge using the ARI the ‘type’ argument now
accepts a new value ‘sdp_label’ which will configure the bridge to add
labels for each stream in the SDP with the corresponding channel id.

– ### app_queue: Preserve reason for realtime queues
Make paused reason in realtime queues persist an
Asterisk restart. This was fixed for non-realtime
queues in ASTERISK_25732.

Upgrade Notes:
—————————————-

– ### app_queue: Preserve reason for realtime queues
Add a new column to the queue_member table:
reason_paused VARCHAR(80) so the reason can be preserved.
